Stationary Time Series Models with Exponential Dispersion Model Margins

Journal of Applied Probability, 1998
We consider a class of stationary infinite-order moving average processes with margins in the class of infinitely divisible exponential dispersion models. The processes are constructed by means of the thinning operation of Joe (1996), generalizing the binomial thinning used by McKenzie (1986, 1988) and Al-Osh and Alzaid (1987) for integer-valued time ...

Generalized exponential‐dispersion process model for degradation analysis under nonlinear condition

Quality and Reliability Engineering International, 2021
AbstractThe regular exponential‐dispersion (ED) process with a nonlinear path can be used to model degradation processes of many products, while it has the shortage that the degradation increment is only age‐dependent, which limits its application in some circumstances. To overcome this shortage, two extensions of the ED process are suggested. For many

On Infinitely Divisible Exponential Dispersion Model Related to Poisson-Exponential Distribution

Communications in Statistics - Theory and Methods, 2007
We construct a univariate exponential dispersion model comprised of discrete infinitely divisible distributions. This model emerges in the theory of branching processes. We obtain a representation for the Levy measure of relevant distributions and characterize their laws as Poisson mixtures and/or compound Poisson distributions.

Poisson Limit Laws for Exponential Dispersion Models

Communications in Statistics - Theory and Methods, 2012
Let ED = {P λ(m), m ∈ M, λ ∈ Λ} be an exponential dispersion model on ℝ d with bounded support parameterized by its domain of the means M and let Λ be its Jorgensen set. In this article, we investigate the asymptotic behavior of P λ(m), when λ tends to + ∞.

Control charts for profile monitoring of within-profile correlations using the Tweedie exponential dispersion process model

Journal of Statistical Computation and Simulation, 2022
In some manufacturing processes, the quality of a product can be characterized by the functional relationship between the response variable and the explanatory variables.

Bayesian analysis for the transformed exponential dispersion process with random effects

Reliability Engineering & System Safety, 2022
The basic exponential-dispersion (ED) process can be used to describe many degradation phenomena, but its degradation increments are only age-dependent, which limits its application especially for the phenomena with state-dependent degradation increments.

Degradation analysis with nonlinear exponential‐dispersion process: Bayesian offline and online perspectives

Quality and Reliability Engineering International, 2022
Exponential‐dispersion (ED) process has been recently introduced and demonstrated as a promising degradation model, which can include classical Wiener, gamma, and inverse Gaussian (IG) processes as special cases.

Optimal degradation-based burn-in policy using Tweedie exponential-dispersion process model with measurement errors

Reliability Engineering & System Safety, 2020
In this paper, degradation-based burn-in for highly-reliable products subject to degradation is studied. Since the common degradation models for burn-in are usually established on the basis of a specific stochastic process, such as Wiener process and ...

Random-Effect Models for Degradation Analysis Based on Nonlinear Tweedie Exponential-Dispersion Processes

IEEE Transactions on Reliability, 2021
The degradation data of highly reliable products are usually analyzed by stochastic process models, such as Wiener process, gamma process and inverse Gaussian process models.
